2017 Teterboro Learjet Crash
On May 15, 2017, a Learjet 35A business jet operated by Trans-Pacific Air Charter crashed while on approach to Teterboro Airport, killing both pilots, the only two occupants on board. The aircraft, flying a repositioning flight from Philadelphia International Airport in Philadelphia, Pennsylvania, to Teterboro Airport in Teterboro, New Jersey, was flying a Instrument approach#Circle-to-land maneuver, circle-to-land approach to land on Runway 1 when it Stall (fluid dynamics), stalled and crashed into a commercial building and a parking lot. The investigation, conducted by the National Transportation Safety Board, determined several factors that led to the crash. The captain of the flight allowed the underqualified first officer (aviation), first officer to be the pilot flying, which was directly against company procedures. Neither flight crew member conducted an approach briefing, which led to a situational awareness, loss of situation awareness and a failure to maintain proper alt ...

Stall (fluid Dynamics)
In fluid dynamics, a stall is a reduction in the lift coefficient generated by a foil as angle of attack exceeds its critical value.Crane, Dale: ''Dictionary of Aeronautical Terms, third edition'', p. 486. Aviation Supplies & Academics, 1997. The critical angle of attack is typically about 15°, but it may vary significantly depending on the fluid, foil – including its shape, size, and finish – and Reynolds number. Stalls in fixed-wing aircraft are often experienced as a sudden reduction in lift. It may be caused either by the pilot increasing the wing's angle of attack or by a decrease in the critical angle of attack. The former may be due to slowing down (below stall speed), the latter by accretion of ice on the wings (especially if the ice is rough). A stall does not mean that the engine(s) have stopped working, or that the aircraft has stopped moving—the effect is the same even in an unpowered glider aircraft. Vectored thrust in aircraft is used to maintain al ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
